Abstract
The present invention is directed to coating additives useful as non-flatting slip-enhancing agents. The additives are the non cross-linked reaction products of (a) an amine represented by the formula NR.sup.1 R.sup.2 H wherein each R is independently selected from the group consisting of hydrocarbyl groups and hydroxyalkyl groups; or by the formula D--(NGH).sub.y wherein D is a multivalent organic radical having 2 to about 30 carbon atoms; each G independently is hydrogen, a hydrocarbyl group, or hydroxyalkyl group; and y is at least 2; provided that if D is an organic radical containing 2 carbon atoms and y is 2, at least one G must be a hydrocarbyl group of 1 to 30 carbon atoms; and (b) a carboxylic acid of the formula B--(COOH).sub.z, or a reactive equivalent thereof, wherein B is a direct link between two COOH groups, a mono- or a multivalent organic radical, and z is 1-5; wherein the resulting product contains at least 2 hydrocarbyl groups each having about 12 to about 30 carbon atoms. The above compositions can enhance the slip properties of a coating composition while retaining the initial gloss.
